I can see the changes Facebook has made in how people communicate right now. This is not a prediction, I can observe it. I know people who no longer use email and exclusively use Facebook for online communication. They share vacation photos with their family and friend sthrough Facebook. They announce life-changing events through Facebook. I, personally, have maintained communication with people that normally I would have just stopped talking to. These are not hypotheticals. These are real, actual changes in how I and others communicate. Facebook has an order of magnitude more users than the previous attempts - Friendster and MySpace - and is able to have much more impact than them because of it.

If you're working in the same space as Facebook, you're not doing yourself any favors by denying its impact. One, it harms your perspective, and two, it harms your credibility.
